Buying Guide for Light Bars for Jeeps
(This is part of our larger Light Bars for Jeep Guide.)
How do I buy a light bar for my Jeep?
A light bar for your Jeep is an excellent way to illuminate your path in low-light situations where headlights just don’t cut it. In addition, KC lights can really improve the custom, trail ready appearance of your rig every day. Since it’s an investment in money and time, we want to help you pick the right light bar for your budget, vehicle and use case based on what we’ve learned with thousands of customers. Let’s dive in.
Which KC light bar is right for my Jeep?
KC HiLiTES offers a number of light bars for Jeep vehicles with a host of different features and options for a variety of budgets. But how do you know which light bar is right for you? Let’s take a look at some KC light bars and explain the differences.
- Gravity® Pro6 LED Light Bar: Inspired by off-road racing and tested by KC racers, the Gravity LED Pro6 Light Bar breaks all performance barriers providing the most durable, robust, and scalable LED light bar design available today. Available in seven widths from 20”–57”, this light bar includes 6” Gravity Pro LED lights, which dominate the rugged appearance and back it up with incredible performance. These light bars are modular, linkable, and curvable all thanks to the patented Infinity Ring linking system.
- FLEX ERA Light Bar: With 7,912 lumens of power per 10" segment, the FLEX ERA LED Light Bar sets a new standard in output, with unprecedented visibility and beam quality — ideal for demanding, high-speed conditions. Any FLEX ERA Bar from 10" to 50" comes standard as a Master Kit with absolutely everything you need to get up and running quickly so you can spend less time in the garage and more time out on the trails. These lights can be linked together to form larger light bars. They can also be made as straight or curved bars.
- SlimLite LED + Xross Bar: This acts as an alternative to a traditional light bar but still provides lots of light output with classic styling.
Curved Vs. Straight Light Bars
You may have heard that light bars can be curved or straight and you might not be sure which to choose. The good news is the KC HiLiTES Gravity Pro6 LED Light Bar and FLEX ERA Light Bars can be used either way on your Jeep. So whether you want a straight-across bar or a curved bar, you have that choice. But let’s look at both options.
Curved
The curved LED light bar design is engineered to provide a wider and more even spread of light. The curvature allows the light to follow the natural contour of the road, enhancing visibility around corners and over uneven surfaces. If you frequently engage in off-road adventures involving winding trails or unpredictable landscapes in your Jeep, a curved LED light bar is an excellent choice.
Straight
Conversely, a straight LED light bar is well-suited for applications where a focused, long-distance beam is crucial. If you’re regularly driving your Jeep on straight trails, at higher speeds, or require a concentrated beam for long-range visibility, the straight design is more appropriate. This configuration is especially effective on open terrains where you need to see far ahead, such as dunes or areas with long straight stretches.

How do you determine how wide of a bar you need and with how many lights?
The appropriate number of lights for a light bar on a Jeep vehicle can vary depending on your specific needs, personal preferences, and local regulations. These are some factors to consider:
Purpose: Think about the light bar’s primary purpose. Is it for off-road illumination, enhancing visibility on dark trails, or for aesthetic purposes? The intended use will help determine the number and type of lights you need. Keep in mind, different uses can also impact which beam patterns you select and more lights require more current draw and may produce more heat.
Mounting options: The number of lights you can mount will also depend on the available space on your Jeep and the type of light bar you choose. Some light bars are designed to accommodate a specific number of lights, while others offer flexibility in customization. Before you purchase, measure the area to see how wide of a bar you can get. This will also assist in determining how many lights you can utilize.
Light output: Determine the level of brightness and coverage you need. More lights can provide a wider and brighter field of vision. But again, remember, it may also consume more power and generate more heat.
Beam pattern: Different lights have various beam patterns, such as flood, spot, or combo beams. Choose the pattern that best meets your specific requirements, whether it's for long-distance visibility or a broader field of view. For example, high-speed driving often necessitates a longer spot beam, whereas slow-speed driving may be better with flood or combo patterns.
Power Supply: Each individual LED light consumes electrical power. Ensure that your vehicle's electrical system can handle the power demands of multiple light bars without overloading the system or draining the battery. Each vehicle is going to be different. Also, the more lights you add, the more complex the wiring and installation become. Proper wiring and installation are crucial for safety and performance.
Aesthetics: Some Jeep owners like the look of a light bar with multiple lights, even if they don't necessarily need them for functional purposes. Your personal taste and style preferences can also influence your decision.
Local regulations: Check your local and state regulations regarding the use of auxiliary lights, as there may be restrictions on the number and brightness of lights that can be used on public roads, as well as if they require covers. In many states, it is common that off-road lights, or lights mounted above the factory headlights, are not permitted on the streets.
Jeep Light Bar Mounting Locations
Light bars are typically mounted in a few different areas including a Jeep’s bumper, roof, and grille. Sometimes, a light bar can even be mounted on the back.
Bumper Mounted Light Bars
Bumper lights represent a versatile auxiliary lighting solution, adaptable to both on and off-road environments, depending upon the appropriate beam pattern selection. In addition, for many Jeeps, the lower, bumper location makes light bars easier to install and adjust than roof-mounted lights. The absence of glare from the hood makes them particularly advantageous in adverse weather conditions such as dust, snow, and rain. Add in an Amber Shield or some Performance Yellow lenses, and bumper-mounted light performance in low-visibility conditions is unparalleled. Just keep in mind that a bumper-mounted light bar can be damaged more easily by trail hazards, stones, and other hazards on- or off-road.
The use of bumper lights necessitates a bumper or mounts capable of accommodating a light bar. The compatibility of Jeep vehicle bumpers varies, with some featuring good spots for optimal light bar placement, while others may not.. Oftentimes, the factory-equipped steel bumpers found on Rubicon or similar edition JKs, JLs, and JTs have plenty of mounting options to fit either a 10” or 20” LED Light Bar. With other bumpers or aftermarket bumpers, the use of specific mounting brackets like our Winch Fairlead Bracket may be required.
Our Ultimate Guide To Bumper Lights serves as an excellent resource, offering a wealth of information to aid in informed decision-making and optimal utilization of this lighting configuration.
Overhead / Roof Mounted Light Bars
The placement of a light bar overhead or on the roof serves a specialized purpose, primarily geared toward long-distance lighting applications. While undeniably effective in certain scenarios, it is important to recognize this configuration may not be universally ideal for all lighting needs. For short- to mid-range coverage, bumper or ditch light locations may be more appropriate.
Overhead lights are optimal for use in performance applications and on vehicles attaining higher speeds. Whether navigating the rugged terrain of Baja, conquering sand dunes, or traversing forest service roads quickly (while adhering to local laws, of course), roof-mounted lights excel in delivering the needed illumination for these environments. Of course, the overhead mounting position also looks great, especially the Gravity Pro6 lights on Jeep Wrangler and Gladiator. It provides that classic KC look!
Also, the incorporation of overhead or roof-mounted lights should complement an existing lighting setup, where short and medium-distance illumination is already achieved through bumper-mounted lights or ditch lights. This multi-light-location strategy enables integration, providing versatility. The overhead mounting position can serve as a strategic choice for the best of both worlds in your comprehensive lighting package.
Our Ultimate Guide To Roof Light Bars really gets into the nitty gritty on this mounting location.
Rear-Facing Light Bars for Jeep
An often overlooked location for mounting an LED Light Bar is on the back of the Jeep, aimed backward. These are also called Chase Bars and are used more as a safety device for others to see you with, than for you to see the terrain with. These bars incorporate amber lights for visibility through dust, as well as red tail and brake lights, along with white reverse lights. This requires a specific Rear-Facing light bar and custom mounting solutions or a roof rack but is a great addition to ensure the safety of you and your passengers.
Jeep Grille Mounted Light Bars
While not as commonplace on Jeeps as on trucks, some owners want to place an LED light bar within a Jeep grille. This unique placement, located slightly higher than a bumper light but lower than an overhead configuration, is often associated with custom or aftermarket Jeep grilles.
Given the typically constrained space in this location, opting for a smaller light bar like the FLEX ERA LED Light Bar can work best. However, measurements must be carefully taken to ensure a proper fit within these applications. It's not just about aesthetics; it's about functionality and seamlessly integrating the light bar into the grille structure.
Care must be taken to guarantee that the wiring for the light bar doesn't impede the operation of cooling fans and remains clear of contact with the radiator. These precautions are essential to prevent potential damage to the light bar's wiring, ensuring an effective integration into the Jeep's grille. So, if you're considering this unique lighting setup, approach it with a keen eye and a thoughtful installation.
Jeep Light Bar Beam Patterns
When it comes to light bar beam patterns for Jeeps, the choice is yours. KC offers light beam patterns such as intense spot, and wide flood patterns. However, there are also combo patterns which can be a good mix. The type of beam patterns you select should depend on your use case.
Choosing the right beam pattern for your Jeep's light bar is crucial, and KC offers a range of options to suit your needs. Whether it's the intense focus of a spot beam or the broader illumination of a flood pattern, there's something for every situation. Combo patterns are also available, offering a versatile mix of both.
Spot Beams
Ideal for high-speed driving, spot beams provide long-range visibility with a narrow focus. They're perfect for situations where you need to see far ahead, like traversing sand dunes or quickly moving down dirt trails. Often mounted on the roof, these beams are sometimes called "pencil beam" lights due to their focused nature.
Combo Beams
To provide the most balanced output of light that spreads both far down, and wide across the trail, combo beams are often used. KC's Pro6 and FLEX ERA light bars offer combo lights, which is a mix of long and short-distance lighting. The Gravity Pro6 lights are modular, allowing for different LED inserts for different beam patterns. Currently, these lights allow for Driving, Spot, and Wide-40 (slightly wider than a Spread Beam) patterns.. The FLEX ERA LED Light BarMaster Kits come pre-assembled in combo beam, but include the spot beam lenses in the box for more customization options..
Aiming Your Light Bar
Properly aiming your LED light bar is key, and the adjustment is mostly up and down. Keep in mind that airing up or down your tires for trail use can impact the aim of your lights as well, as can lift kits or larger wheels and tires.
For bumper-mounted bars, start with the beam set low and gradually adjust upwards for a balanced blend of long, mid, and short-distance lighting.
Overhead lighting should start high and be lowered for optimal distance. Slowly aim it lower and lower until it overlaps the beams from your other lights by about 15-30%.
Grille-mounted bars fall in between.
Remember to consider any existing lights on your Jeep, ensuring that your light bar complements them effectively.
Power Consumption / Battery Drain
LED light bars stand out for their energy efficiency, especially when compared to traditional halogen or HID lights. They offer bright illumination while using relatively low power. However, it's essential to consider their power consumption, particularly if you're planning to install multiple bars or additional electrical accessories on your Jeep.
It's crucial to ensure your vehicle’s electrical system is well-maintained. This involves having a fully charged battery, a properly working alternator, and the correct installation of the light bar. For example, our largest 57” Gravity LED Pro6 light bar draws only 15 amps. But, when you add other accessories like winches, stereos, or air compressors, it's vital to check that your Jeep's electrical system can handle the load.
Be aware of the duration you use your light bar when the engine is off. The engine powers the alternator, which in turn recharges the Jeep’s battery. Under normal circumstances, a healthy battery and alternator should easily support your LED light bar’s power demands. However, using the light bar for extended periods without running the engine can lead to battery drainage. So, while LED light bars are efficient, responsible usage is key to avoid straining your vehicle's battery.
Installation of Light Bars on Jeeps
KC light bars are designed to be universal, but we also offer Jeep-specific light bar kits tailored to your vehicle's year and model. You can easily find the right brackets for many common setups using the KC light finder tool here. If you do not have a vehicle in the KC light finder, you can purchase light mounts like the KC Xross Bar and pair them with the proper vehicle-specific mounts or find a local fabricator to custom-make them for your vehicle. Many off-roaders are surprised by how affordable custom fabricated mounts can be—and you’ll be guaranteed of a truly unique build having taken this extra step.
No matter which KC light bar you choose for your Jeep, we offer comprehensive instructions and a variety of helpful videos to guide you through the installation process. It's crucial to follow these instructions carefully to avoid any accidental damage to your vehicle's electrical system.
Additionally, when installing your wiring, ensure that wires are kept clear of hot areas (like the engine), sharp edges (such as pinch welds), and moving parts (like belts and fans). Also, be sure to secure your exterior wiring to prevent it from getting snagged on trail obstacles, such as low-hanging branches or brush.
Jeep Vehicle Warranty
If you have a newer Jeep with a manufacturer warranty, you may be wondering if adding a light bar will void the warranty. The short answer is “no.” There are a number of consumer protection acts, such as the Magnuson-Moss Warranty Act, that help protect owners from manufacturers voiding warranties by adding aftermarket accessories.
Again, it’s important to follow KC’s installation instructions properly to avoid any mishaps that could cause an electrical issue with the vehicle. In most cases, if you install the item improperly and it causes damage, the installer will have to assume the responsibility, and will not be covered under a manufacturer warranty—Jeep or KC included.
Street Legality
While KC offers street-legal LED driving and fog lights, in most cases, LED light bars aren’t something you can legally use on the streets. Every state has different laws with regard to LED lighting, so we advise you to check out our street legality page. So if you’re asking “Are Light Bars Legal?” We’ll help you answer this question.
Light Bar Compatibility with Other Accessories
Before you buy a light bar for your Jeep, it's important to think about the other accessories on your vehicle and how they might affect the installation of the light bar. Check the area where you plan to mount the light bar—whether it's on the roof, bumper, or grille—and consider if any existing accessories might block or interfere with it. These could include:
- Roof racks
- Other lights
- Winches
- Tow hooks
- Bull bars
Some products, like the FLEX ERA LED Light Bars, are often more adaptable when it comes to fitting in with other accessories due to their compact size and flexible mounting options.
However, in many cases, you can successfully install LED light bars alongside other Jeep accessories. Just make sure to thoroughly research your specific application and its setup to ensure everything fits together properly..
Jeep Light Bars vs Ditch Lights
Jeep light bars and ditch lights are two different things. Where light bars are mounted either overhead or on the bumper (occasionally in the grille), ditch lights are mounted near the vehicle’s A-pillar or windshield. They’re typically angled outward about 45 degrees from the vehicle. They are intended to help illuminate the “ditch” or areas alongside the Jeep.
Jeep Light Bars - Avoiding Vibration and Noise
When installing a light bar on your Jeep, it's crucial to minimize vibration and noise for the best experience. Here are a few ways you can achieve this:
- Adhere to the installation instructions provided with your light bar or those available on our website. Our products are designed to be quiet and minimize vibration, thanks to our specially engineered mounts.
- Ensure there's adequate space between the mount and the vehicle. This spacing acts as a buffer, helping to reduce vibration.
- Properly run and secure the wiring. This not only ensures safety but also helps to reduce wind noise.
If you notice vibration or wind noise after installing your light bar on your Jeep, small adjustments in the bar's aim or height can often remedy these issues. Remember, attention to detail during installation can make a significant difference.
Security
There’s no sure-fire way to keep your Jeep LED light bar from getting stolen. However, there are a few things you can do. You can use security nuts. These can make it harder for thieves to remove the bolts attaching the light bar to the Jeep. Alternatively, you could even weld bolts to the brackets, although this can be a bit extreme.
